Greenmist Quest question

[holaneko]

i have hero's khukri and stupendous tome, and it says to turn them into arch duke Xog but he ate them 2 months ago, and i just got them recovered from GM, so i don't want to fail this time.

i read the detail side of the quest, and i guess iam supposed to talk to him, and i wrote as it was written, but arch duke isnt talking back to me...

can anyone help enlighten me?
